Chapter 1 - Redox Equilibrium
🌷Electrolysis of Aqueous Solutions

Electrolysis of : CuSO4💙 solution using copper electrodes (active electrode)🤎

......

Question : Why the blue colour of CuSO4 solution does not change? 💙

✨Answer (pg 44 tb)
🫐The concentration of copper (ii) ions, Cu2+ remains the same.
🫐The rate of ionisation of copper, Cu at the anode is the same as the rate of discharged copper(ii) ions, Cu2+ at the cathode.

🌷Oxidising Agent:
👉that oxidises the other substance
👉undergoes reduction
👉oxidation number decreases
👉loses O2
👉gain H2
👉gain electron

Examples:
1⃣💜Acidified potassium manganate (VII), KMnO4

2⃣Acidified potassium dichromate (VI), K2Cr2O7

3⃣💛Chlorine water, Cl2

4⃣🤎Bromine water, Br2

5⃣Acidified hydrogen peroxide, H2O2



🌷Reducing agent :
👉 that reduces the other substance
👉undergoes oxidation
👉oxidation number increases
👉gain O2
👉loses H2
👉loses electron

Examples:
1⃣Potassium Iodide, KI

2⃣Potassium Bromide, KBr

3⃣Iron(ii) sulphate, FeSO4

4⃣Reactive metals (e.g. Zn and Mg)

5⃣Sulphur dioxide, SO2
